The U.K. Passport Service said Friday it will forbid open-mouthed smiles on passport pictures, one of several rules introduced to comply with strict new U.S. standards. Smiles, sunglasses and hair slanting across the eyes are forbidden because they may confuse security cameras used to scan faces.

The new passports will also be fitted with a chip containing the facial image and other data to help stamp out passport fraud.
